Following Clinton's defeat, the Republican National Committee is bashing her for losing to "a 74-year-old socialist":

Losing six of the last seven states at this stage of the race once again highlights the fact Hillary Clinton is a weak candidate running a campaign with no clear message. For months we heard from the Clinton camp that they'd have the nomination wrapped up by March, but as we head into April she's still struggling to put away a 74 year-old socialist who never before sought office as a Democrat.

Cruz is addressing his supporters in Wisconsin and has called his latest win a "turning point, a rallying cry." He's noted his recent wins in Utah, Colorado and North Dakota and has made the time to take a swipe at Democratic frontrunner Hillary Clinton.

"Just how significant is tonight? Well just today, our campaign has raised over $2m. People all over the country going to tedcruz.org," he said, adding that he is convinced he can reach the 1,237 delegates needed for the nomination – despite the maths not being on his side.

"We will win a majority of the delegates, and together we will beat Hillary Clinton in November," Cruz added. "Tonight was a bad night for Hillary Clinton. It was a bad night for her in the Democratic primary and it was an even worse night for her in the Republican primary."

Tonight, Wisconsin has lit a candle guiding the way forward. Tonight, we once again have hope for the future.

The Democratic race has been called for Bernie Sanders. The Vermont senator has been on a roll, accumulating win after win. Sanders has taken six of the last seven states, yet remains behind Clinton in delegate count due to a large number of superdelegates supporting the former secretary of state.

Wisconsin has reportedly received the highest voter turnout in a presidential primary since 1980. Thankfully that has not resulted in problems at the polls. Officials project turnout at 40% of eligible voters.

Democratic runner Bernie Sanders recently had a meeting with the editorial board of the New York Daily News in hopes of getting their endorsement ahead of the New York primary on 19 April. And it did not go well.

Throughout the interview, Sanders appeared to dodge direct questions about his proposals and attempted to redirect to his normal rally talking points. At one particular moment, when discussing trade deals, Sanders even admitted to agreeing with GOP rival Donald Trump.

While the Vermont senator seems ready to move forward on his campaign promises, he may not have completely worked out how these promises will play out. The Daily News asked Sanders about the consequences of breaking up big banks, particularly for those that work in the industry, and he failed to look past his proposal to what could happen to those workers.

Daily News: So if you look forward, a year, maybe two years, right now you have...JPMorgan has 241,000 employees. About 20,000 of them in New York. $192bn (£135.5bn) in net assets. What happens? What do you foresee? What is JPMorgan in year two of...

Sanders: What I foresee is a stronger national economy. And, in fact, a stronger economy in New York State, as well. What I foresee is a financial system which actually makes affordable loans to small and medium-size businesses. Does not live as an island onto themselves concerned about their own profits. And, in fact, creating incredibly complicated financial tools, which have led us into the worst economic recession in the modern history of the United States.

Daily News: I get that point. I'm just looking at the method because, actions have reactions, right? There are pluses and minuses. So, if you push here, you may get an unintended consequence that you don't understand. So, what I'm asking is, how can we understand? If you look at JPMorgan just as an example, or you can do Citibank, or Bank of America. What would it be? What would that institution be? Would there be a consumer bank? Where would the investing go?

Exit polls show that a quarter of GOP voters are excited by Trump's candidacy, but 40% are scared about what he would do as president. Meanwhile, only about 10% of voters say the same of Cruz or Kasich.

Early results from exit polls also reveal that nearly six in 10 Republican voters believe the party should nominate the candidate with the most support in the primaries in the case of a brokered convention. Meanwhile, four in 10 say the party should nominate the person who delegates believe would be the best candidate.

Welcome to our live coverage of tonight's Wisconsin primary. Candidates from both parties will compete for the support of voters in the Badger State, with frontrunners Donald Trump and Hillary Clinton potentially headed for defeat. The two currently lead their parties in delegate count, and despite possibly losing tonight, could continue to rake in delegates.
